Indigenous communities face the loss of both physical and cultural resources. Glacies hold spiritual consignace for many Andeen peops, who view them as deities (apus). The disappearance of glaciers represents nott only a material loss but also a profound cultural erosion.

Mitigation andAdaptation: Pathways Forward

Tackling the glacier crisis requires a two-pronged approach: agressive liberation to reduce greenhousie gas emissions and robutt adaptation to managee the unavoidable impacts. While global liberation is essential, local and national actions can make a signitant difference ce te in reducing librability.

Reducing Emissions at Scale

Protecting andRestoring Ecosystems
